Description
The RX7 engine, also known as the 13B-REW, is a 1.3L twin-rotor rotary design producing roughly 276 horsepower and 231 lb-ft of torque. Compact and efficient, it features a sequential twin-turbo system that maintains power throughout the RPM range. Found in the Mazda RX-7 FD3S, it’s famous for responsiveness, rev-happiness, and tuning potential. For other rotary or high-performance options, explore our used engines or match it with used transmissions for a full swap setup.
13B-REW fitment is specific to the FD RX-7 (1992–2002). The North American specification and Japanese domestic market specification engines differ in boost settings and emission equipment. The engine uses a specific rotary-design cooling system and oil injection metering pump that are critical to correct operation. Our application review confirms the correct 13B-REW for your RX-7 before it ships.
FD RX-7 owners comparing a used engine, a remanufactured engine, and an OEM engine for the 13B-REW understand that rotary engine specialists command premium rebuild rates. Choosing a used Mazda RX-7 13B-REW engine from a verified low-mileage FD RX-7 gives you the factory twin-sequential turbo rotary as an OEM engine — the original Wankel rotor architecture, the factory sequential turbo system, the factory Mazda engineering — at a price that makes maintaining one of the most distinctive and rewarding sports cars ever made economically practical. No remanufactured engine from a single-turbo 13B core delivers the 13B-REW’s specific twin-sequential factory identity.
Every used Mazda RX-7 13B-REW engine ships with up to a 90-day warranty and arrives within 2 to 5 business days. Installation is not included. Rotary-specialist installation is required for this application. These are genuine Mazda OEM engines, and we stand behind every unit.
